INTRODUCTION This paper describes, for the first time, the outcomes of patients undergoing total hip replacement for acute fractured neck of femur (#NOF) as recorded by the National Joint Registry of England and Wales (NJR). METHODS In the NJR we identified 1,302 of 157,232 Hospital Episode Statistics linked patients who had been recorded as having a total hip replacement for acute #NOF between April 2003 and November 2008. RESULTS The revision rate at five years for fully uncemented components was 4.1% (95% confidence interval [CI]: 2.2-7.3%), for hybrid it was 2.2% (95% CI: 0.9%-5.3%) and for fully cemented components 0.9% (95% CI: 0.4-2.0%). Five-year revision rates were increased for those whose operations were performed via a posterior versus a lateral approach. The Kaplan-Meier estimate of 30-day mortality was 1.4% (95% CI: 1.0-2.4%), which is over double the 30-day mortality rate for total hip replacement identified by the Office for National Statistics. The mean length of stay was also increased for those undergoing total hip replacements for #NOF compared with non-emergency indications. CONCLUSIONS Our data suggest that total hip replacements for acute #NOF give comparable results with total hip replacements for other indications.

Using the Casebeer system for refractive keratotomy, we obtained 20/40 or better uncorrected visual acuity in 96% of eyes with low to moderate levels of myopia. However, a significant number of enhancement procedures, 36% overall, were required to achieve this level of success. Hyperopic shift remains a significant concern following radial keratotomy procedures.
